People with visual impairments face significant challenges in navigating their surroundings safely and independently. Traditional mobility aids like white canes have limitations in terms of obstacle detection, especially at head or knee level. To enhance mobility and safety, electronic footwear integrated with sensors and alert mechanisms can serve as a smart assistive device.
This project aims to design electronic footwear that can detect obstacles using ultrasonic sensors and alert the user through vibration or audio feedback. The system provides real-time obstacle detection, improving navigation efficiency and reducing the risk of accidents.
The core principle behind this system is ultrasonic distance measurement and feedback alert:
Ultrasonic sensors emit sound waves and measure the time it takes for the echo to return.
The distance to an obstacle is calculated based on this time.
If the obstacle is within a predefined range (e.g., <1 meter), the system triggers a vibration motor or buzzer to alert the user.
Some systems use multiple sensors to detect objects in different directions (front, left, right).
Microcontrollers process the sensor data and control the feedback mechanism.
Power ON System
Footwear is powered using a small battery pack.
Distance Measurement
Ultrasonic sensor continuously scans for obstacles ahead.
Data Processing
Microcontroller (e.g., Arduino Nano) receives sensor data and calculates the distance.
Decision Making
If the obstacle is closer than the set threshold:
Vibrator or buzzer is activated.
Intensity or frequency may vary based on distance.
User Feedback
The user receives alerts through vibration (in the shoe sole or strap) or sound (in an earphone or buzzer).
Optional Upgrades
GPS module to track user movement.
Bluetooth module for mobile app alerts.
Rechargeable battery with USB charging.
